Tekstur tanah
Tekstur tanah adalah klasifikasi secara kualitatif mengenai kondisi suatu tanah berdasarkan tekstur fisiknya. Pengujian dan penerapan tekstur tanah diterapkan di lapangan maupun di laboratorium. Kategori utama dari tekstur tanah yaitu tanah berpasir, liat atau lempung, dan geluh atau lanau, berdasarkan distribusi ukuran partikel tanah yang didapatkan dengan pengayakan. Kualitas tekstur tanah yang didapatkan bisa digunakan untuk berbagai penerapan, misal komoditas pertanian yang cocok untuk ditanam hingga kondisi dan perubahan lingkungan.
Klasifikasi berdasarkan USDA
suntingJenis tanah | Diameter partikel |
---|---|
Liat | less than 0.002 |
Lanau | 0.002–0.05 |
Berpasir sangat halus | 0.05–0.10 |
Berpasir halus | 0.10–0.25 |
Berpasir sedang | 0.25–0.50 |
Berpasir kasar | 0.50–1.00 |
Berpasir sangat kasar | 1.00–2.00 |
